I had the upgrade done on our 2013 Leaf, mid December(in Raleigh NC area). As I remember, you need to generate carwings id and password on Nissan Connect web site. Btw, you would use Nissan ConnectEV app to connect back to the car from phone. It took a while for me to figure all of this out. As we bought the car used and had to jump through some more hoops in proving to Nissan that I am the actual owner!

I received a letter mailed by Nissan informing me the ATT 2G will stop working and for $199 Nissan will install a new module that will replace the old 2G module. They didn't say who will pay any monthly service charges for the use of the cell network or which network provider it supports. I suppose it is the same old ATT. What I need is a WiFI module installed so the service provider becomes generic and without charge. I have a T-Mobile "hot-spot" I pay $20/month. I use it for cell phone and iPOD streaming music from Accuradio or Pandora. If my 2011 Leaf would use WiFi instead of ATT to connect to the Internet, it would be great! Plus it wouldn't be dedicated to a single service provider.

A -2F morning here in NH with a non-functioning CARWINGS precondition feature made the loss of the 2G network real for me... I'm with redhat... I'm a bit anxious spending $199 for a 3G module with no mention of service fees. I'm OK with the 'co pay' as a onetime fee if the connectivity service remains free. I'd just hate to spend the capital to find out they'll be hitting us with monthly fees.. Did I miss something? Anyone out there working on a wifi or bluetooth third party module?

I'm in the same boat, complicated by all the changes Nissan has made since 2011. The web site has changed from CarWings to Nissan Owner's Portal, and possibly to NissanConnect. The original service used a 10 character username. The current web site uses my email address as username, but I cannot enter that username into the car which limits that field to 16 characters.

Using my original short username and either the original CarWings password or the new NissanConnect password fails. But the unhelpful error message is that the car cannot connect to service. Which could mean either that the password is incorrect, or that the old username cannot be used, or that the radio actually cannot connect.

The login for the car is different than the one for the app/website. You can get the login from the website.Go to https://owners.nissanusa.com/nowners/ , log in with you email and password, under "Manage Vehicle" click on the link for "Looking for your NissanConnectEV PIN and Password?", and you can use this login information on the car. If you get any errors at this point, use the contact information from https://www.nissanusa.com/apps/contactus and call them at (877) NO GAS EV (or 877-664-2738) with options 1 followed by 6 to reach a specialist. It seems that quite a few of us are having trouble since the 3G upgrade, so I recommend calling in and requesting escalation if you have trouble. Hopefully if enough people request escalation then someone will actually take notice and fix it.

UPDATE: My 3G TCU is working correctly. I'm not sure if they updated something on the server side, it just needed more time, or if Nissan Corporate went in and manually fixed it, but it's working as expected now.

It seems the AT&T 2G service in my part of the SF Bay Area stopped working sometime last week.

If I could get a free SIM w/no monthly service fee, that's obviously FAR preferred to paying $199.

I'm sure T-Mobile will give you a SIM for free. You will be responsible for the ongoing monthly connection fee to the T-Mobile network. Whether or not it will work is unknown. Maybe you can find someone with T-Mobile service and borrow their SIM card long enough to test it in the 2G TCU (assuming it has an accessible SIM card).

The 2G service here was turned off last Wednesday (the fourth). I opted to pay the $199 for the TCU replacement.

I actually have 2 T-Mobile SIMs w/service, but would rather not have to remove the glovebox again to try it... Hoping someone else already did.

And, I don't know if I can get a T-Mobile SIM w/a low enough monthly fee (or one w/free monthly service) to make it worth it, assuming it even works. There could need to be APN configuration on the car (nav system) side.
